EYELE TING-IVEAGHINE.

Application filed January 2 1, 1918.

nection with the accompanying drawings, is:

a specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to fastener inserting machines and is hereinillustrated as em-.

bodied in a machine for setting eyelets, hooks, or the like, in sheetmaterial.

Eyeleting machines of the type in ques tion conunonly include arcciprocable eyelet presenting device and a movably mounted raceway fordelivering eyelets to said pro senting device, means being provided formoving said raceway into and out of the path of the presenting device sothat the endmost eyelet in the raceway may be threaded by the presentingdevice and the raceway then drawn aside to prevent interference betweenit and the presenting de vice. in such machines, it is very desirable,if not indeed essential, that the movements of the raceway shall be socontrolled that the time of movement of the raceway shali be alteredduring the cycle of movement of the presenting device.

An object of this invention is to provide improved means for operativelyconnecting a fastener positioning or presenting device to a fastenerraceway which will secure the desired result and avoid interferencebetween the raceway and the presenting de' vice. 7

In fastener insertingmachines in general, and particularly in machinesof thetype in question, it is frequently necessaryto turn the machineover slowly in order to test the adjustment or watch the operation ofthe various parts. Commonly it has been necessary to remove the beltfrom the driving pulley in order to accomplish thls result, and theremoval and replacement of this belt is inconvenient and involves dangerof accident to the operator.

Specification of Letters Patent.

Serial No. 212,972.

In'view of the latter conditions another object of the invention is toprovide novel means arranged to lock the clutch in open or disconnectedposition so that the machine may be turned over by hand while the driv-111g member of the clutch is rotating, without danger of accidentalcoupling of the driving and driven members of the clutch.

Other features of the invention will be come apparent upon aconsideration of the following specification taken in connectio with theaccompanying drawings, in which Figure 1 is a side view of the machinewith parts broken away and showing the op- 6' crating parts in stopposition;

Figs. 2 and 3 are angularperspectives of the raceway actuating mechanismwith the parts in stop position in Fig. 2, and in another extremeposition in Fig. 3; 7e

Fig. 5 is a perspective with parts broken away showing the clutchmechanism; and

Fig. 6 is a detail of part of said mecha- 7 nism.

The ope ating parts of the machine are mounted upon a frame 10 and themoving parts are actuated bymeans of power supplied from a shaft 12.Loosely mounted upon this shaft is a belt pulley lei provided with aplurality of studs 16, each of which has a flattened face adapted toengage the flattened face of a pin 18 which passes through a hole in asleeve 20 fixed to the shaft. The sleeve 20 is surrounded by a bushing22 which fits within an annular pro jection 24 upon the belt pulley 14.

Fixed to one end of the pin 18 is a wedgeshaped semicircular member .26which is provided with a lug 28 adapted to be received within a slot inanintegral. extension 30 of the sleeve 20. This pin 18 andthewedge-shaped member 26 must therefore turn with the shaft 12, but maybe given a sliding movement axially of the shaft. A spring 32 isprovided which is tensioncd to hold the pin 18 normally inengagementwith one of the studs 16, and when so engaged, power will be supplied bythe pulley to the main shaft. When it is desired to stop the machine, arod 34 is caused to pass into the path of movement 'ofthe wedge-shapedmember 26 and, by engagement'with the sloping surface thereof, it drawsout the pin 18 against the tension of the spring 32. This rod 3 r isarranged to be depressed by 'means ofa treadle rod 36, and is normallypressed upwardly into the path of movement of'the wedge-shaped member 26by means of a spring 88. The machine may be started,

therefore, by depressing the treadle rod 36' to allow the pin 18 toengage one of the studs16. After the treadle rod is released,

however, the machine will be stopped atthe completion. of the currentrevolution: by

reasonof the engagement of .the rod withthe wedge-shaped member as abovede scribed A locking pawl 40 is pivotally mounted upon the member 26 andthis pawl may be moved into engagement with the end of the extension 30of the sleeve-2O to prevent operative movement ofnthe pin 18 intoengagement with one of the studs 16.

The machine may then be-turned over by hand for ad ustment of theoperating parts or other purpose without danger even though the beltcontinues to' drive the pulley 14. a a

In the forwardqpart of the frame there is mountedfor verticalreeiprocation,-the usual plunger 4-2 carrying aniupper set 142: which isprovided with. the customary spring 54:,- which. are straightened bymeans of an i eccentric rod 56,. which is actuated in turn by means ofan eccentricupon the shaft 12.

lhe'lower set is mounted in alinement with the upper set upon aforwardly projecting stud 62' which is supported upon the-frame in anysuitable manner.

Eyelets are supplied to the upper set by means of a hopper 64c andraceway 66 which are movable as a single piece pivoted at 68 upon theframe'of the machine. it part of,

the usual agitator mechanism for stirring the eyelets in the hopperis-shown at '70."

The raceway 6 6 is urged, by means. of a. spring 7 T2 surrounding a rod74: pivotall attached to the raceway, into a position such that thelowermost eyelet in the raceway, which is retained therein by theusualspring actuated finger," is in alinement with the spindle 416, as showninr liig. 3. The ultimate positionof the raceway whenmoved inwardly bymeans of the spring 721s con to the frame of the machine.

trolled by the engagement of an adjustable stop 76 with a resilient,member 7 8 attached V llovement of the raceway into and out of the pathof re ciprocation of the upper set is controlled by a ,bell crank lever80 pivotally mounted with an arm '82 engaging one side'of the racewaysupport and with an oppositely ex tending arm Swhieh cooperates with raroller 87 upon the lower end of an arm 86 which is fixed upon the shaft50. The outer end of the arm 84 is, however, provided with a slidingblock 9O which is retained movably by means of screws passing throughslots in said block. This member 90=is provided witha short and abruptcam surface 92 joining'two non-actuating faces 9st, 96. Upon theopposite side of the block 90 there is provided a pin 98. which isarranged to be interposed between the forked ends 100.

o-fxan actuator 102, pivoted upon the back sideof the arm 8%. The upperend'of this actuatoris recessed, as shown in Fig. a, and adapted toreceive loosely a stud 10 1 upon the crank 86. 7 V V The operation ofthe machine will be as follows:

Assuming that the parts are in the position shown in Fig. l, and thatthe treadle is 7 about to be depressed so asto allow the-pin 18 toengage one of the studs 16 upon the V mosteyelet in the raceway, butbefore the:

set 44C contacts with the end of the raceway, the latterwi-ll be moved,aside by reason of the actuation of the bell crank lever 80 from the arm86. During this part'of the cycle ofoperation, the'roller upon the lowerend of the crank 86 will ride up the cam sur face 92 to the higher level941- on'the block' .90- and thereby pullthe raceway out of alinementwith the upper set. The upper set will continue to descend, and,'byco-action with vthe upsetting die 60' secure the eyelet in theworlrinterposedbetween'the sets. its the shaftcontinues to rotate, thetoggle '52, will be again broken and theplunger42 with its set 14willberaised 'out ofengagement with th-e 'work; At about'the same time,the raceway'66 will be'movedinto alinement with the set by means of ,the

spring 72 so 'thatwhen the cycle of the machine'is-repeated, thelowermost eyeletin the raceway may be pagain threaded by the spindle 4e;This-return movement of the raeeway,'however, is controlled by the bell.crank lever 80; In this connection it should upon the frameofthe'machine and provided the be noted. that the actuating face or rise92 of the ca1n-plate is relatively near the front end of the latter, inconsequence of which the roller 87 does not have so far to travel, inmoving from front to rear, before encountering the rise, as it doesafter leaving the rise. 'i he clfect of the rise is to displace the endof the raceway quickly from the path of the upper set when the latterhas traversed far enough to .insert the tip of the spindle through theeyelet barrel. As the set is about to complete its downstroke, thelinger 10 lshifts the cam-plate forwardly so that, during the upstrokeof the set, the roll 87 will have farther to travel before reaching theface 92 than it had to travel after leaving said face during thedownstroke. Thus beginning of the return movement of the raceway ispostponed. until the upper set has reached a higher level than itoccopied when the raceway was removed from its path, and the tip of thespindle is therefore enabled to clear the leading eyelet in the raceway.After the return movement of the raceway has begun the finger 10 ishifts the cam-plate to the rear, such shifting ending simultaneouslywith the upstroke of the upper set.

An important feature of this mechanism the relatively abrupt char actorand postponed action of the active portion 92 of the cam-plate. This, inconjunction with the shifting of the camplate, which begins after theportion 92- has acted, postpones the be ginning of the return movementof the raceway cnough to clear the spindle during the upstroke.
